Description

Technical Field

[0001] The invention relates to the technical field of spraying medicine, in particular to a fruit and vegetable spraying device. Background Art

[0002] In current agricultural production practices, effective prevention and control of fruit and vegetable pests and diseases is a core element to ensure the healthy growth of crops and increase yields. However, when using traditional handheld sprayers for spraying, there is often a problem of residual pesticides drifting into the atmosphere or depositing in the soil, which not only leads to a huge waste of pesticides, but also raises concerns about environmental pollution. Especially in large-scale spraying operations, the widespread drift of pesticides and contact with the soil not only weakens the effect of pest control, but also poses a potential pollution risk to the surrounding environment.

[0003] In order to meet the above challenges, a variety of improved versions of fruit and vegetable spraying equipment have emerged in the current technology field. These devices attempt to capture and absorb excess pesticides by adding baffles around the spraying area. However, the limitation of this type of method is that they can only intercept pesticides that directly touch the baffles, and the interception range is relatively limited. In addition, if the intercepted pesticides are not properly handled in time, they may evaporate or drip again, and continue to threaten the environmental quality of the atmosphere and soil. Summary of the invention

[0004] In view of the above-mentioned prior art, the present invention provides a fruit and vegetable spraying device, which can effectively absorb excess pesticides, thereby significantly reducing the amount of pesticide residues in the air and reducing the potential pollution of the pesticide to the soil.

[0005] To achieve the above object, the technical solution of the embodiment of the present invention is implemented as follows:

[0006] A fruit and vegetable spraying device comprises a spraying system and a residual medicine recovery system, wherein the spraying system comprises a spray head for spraying medicine, and the residual medicine recovery system comprises an annular tube, a pump body and a recovery tank, wherein the annular tube is located at the outer periphery of the spray head, the annular tube is communicated with the pump body, the pump body is communicated with the recovery tank, an isolation cylinder, a guide block, a diverter block and a baffle are arranged in the recovery tank, a plurality of the isolation cylinders are coaxially arranged in the recovery tank, the isolation cylinders are provided with openings, the openings of adjacent isolation cylinders are staggered, an air flow channel is formed between the isolation cylinders, the guide blocks are arranged at intervals in the air flow channel, the diverter blocks are arranged between the guide blocks, the diverter blocks are in a water drop shape, the end of the diverter block is a circular arc portion, the head end is a tip portion, the tip portion faces the direction facing the air flow, the guide block is provided with an arc groove, the arc groove is concentric with the curved surface of the circular arc portion, and the baffle is arranged on the opposite side of the guide block.

[0007] Furthermore, the guide block is triangular, the first side of the guide block is connected to the side wall of the airflow channel, the second side is provided with the arc-shaped groove, the arc-shaped groove faces the direction of the airflow, the baffle is provided opposite the third side, and the third side of the guide block is parallel to the baffle.

[0008] Furthermore, a plurality of metal sheets are provided between the baffle and the side wall of the airflow channel. The metal sheets are parallel to the baffle, one end of the metal sheets is connected to the side wall of the airflow channel, and the other end is located on a plane parallel to the side of the diverter block.

[0009] Furthermore, a plurality of water collecting grooves are provided at the bottom of the recovery tank, and the water collecting grooves are provided along the bottom of the inner wall of the recovery pipe and the bottom of both sides of the isolation cylinder. The water collecting grooves are connected to the drainage grooves, and the drainage grooves are connected to the drainage pipes.

[0010] Furthermore, the drain pipe is provided with a valve.

[0011] Furthermore, a refrigerator is provided at the center of the recovery tank.

[0012] Furthermore, the refrigerator includes a heat conducting sheet, a heat conducting tube and a cooling box, wherein a refrigerant medium is arranged in the cooling box, the cooling box is connected to the heat conducting tube, and the heat conducting tube is connected to the heat conducting sheet.

[0013] Furthermore, the heat conducting sheet is a C-shaped structure, and a plurality of the heat conducting sheets are nested to form flow channels through which air can pass, and the openings of adjacent heat conducting sheets face opposite directions.

[0014] The beneficial effects of the present invention are:

[0015] Under the driving force of the pump body, the airflow in the annular tube is effectively sucked, driving the medicine around the nozzle to be sucked into the annular tube, and smoothly introduced into the recovery tank along the established pipeline. Inside the recovery tank, the airflow first passes through the airflow channel between the baffle and the guide block, and is then divided into two independent airflows by the diverter block, traveling along the left and right sides of the diverter block respectively. When the two airflows encounter the arc groove of the next guide block, their travel direction changes significantly, and finally a violent collision occurs at the end of the diverter block. In the airflow channel, this multiple collision greatly increases the flow resistance of the airflow, especially in the channel area close to the pump body, where the airflow pressure rises significantly. This pressure change causes the moisture in the airflow to begin to condense, and drives the drug components to adhere to the side walls of the channel in the form of water droplets. At the same time, the airflow at the opening position of the isolation tube in the recovery tank is counteracted and mixed. This design further accelerates the condensation process of water vapor in the airflow and effectively separates the drug components carried by the airflow. Through these mutually colliding areas, the water vapor in the air flow can be efficiently condensed, thereby effectively separating the pesticide from the air flow, which not only avoids the decline in air quality, but also protects the soil environment from the impact of pesticide residues.

[0023] Please refer to the attached Figures 1-2 The present application provides a fruit and vegetable spraying device, comprising a spraying system 1 and a residual medicine recovery system 2, wherein the spraying system 1 comprises a spray head 3 for spraying medicine, and the residual medicine recovery system 2 comprises an annular tube 4, a pump body 5 and a recovery tank 6, wherein the annular tube 4 is located at the outer periphery of the spray head 3, the annular tube 4 is connected to the pump body 5, the pump body 5 is connected to the recovery tank 6, and the recovery tank 6 is provided with an isolation cylinder 7, a guide block 8, a diversion block 9 and a baffle 10, a plurality of the isolation cylinders 7 are coaxially arranged in the recovery tank 6, and the isolation cylinder 7 is provided with an opening 1 1. The openings 11 of the adjacent isolation cylinders 7 are staggered, and an airflow channel 12 is formed between the isolation cylinders 7. The guide blocks 8 are arranged at intervals in the airflow channel 12. The diverter blocks 9 are arranged between the guide blocks 8. The diverter blocks 9 are in a teardrop shape, and the end of the diverter block 9 is a circular arc portion 13, and the head end is a tip portion 14. The tip portion 14 faces the direction of the airflow. The guide block 8 is provided with an arc groove 15, and the arc groove 15 is concentric with the curved surface of the circular arc portion 13. The baffle 10 is provided on the opposite side of the guide block 8.

[0024] The spraying system 1 is used to spray fruits and vegetables, and the medicine is evenly sprayed through the nozzle 3 and covers the surface of the fruits and vegetables. An annular tube 4 is arranged outside the nozzle 3. With the help of the suction force generated by the pump body 5, the annular tube 4 effectively extracts the medicine mist around the nozzle 3, guides it into the inside of the annular tube 4, and finally transports it to the recovery tank 6 along the preset pipeline. Inside the recovery tank 6, the air flow channel 12 is divided by the isolation tube 7 to form a multi-layer structure. The airflow starts from the outermost air flow channel 12, passes through the opposite side, and then turns through the opening 11 to enter the adjacent inner air flow channel 12, and so on. At the opening 11 of each layer, the airflow directions are opposite and intersect. This design enhances the mixing of the airflow, promotes the condensation of water vapor in the airflow, and effectively separates the medicine components. An exhaust pipe is installed in the center of the top of the recovery tank 6 to release the pure air remaining after condensation.

[0025] In the airflow path, the baffle 10 and the guide block 8 work together to guide the airflow to pass between the baffle 10 and the guide block 8, and the diverter block 9 divides the airflow into two, flowing along the left and right sides of the diverter block 9 respectively. As the airflow passes through the arc groove 15 of the subsequent guide block 8, its flow direction is adjusted again, causing the two airflows to collide at the end of the diverter block 9. In the airflow channel 12, multiple collisions significantly increase the flow resistance of the airflow, and the pressure in the area close to the pump body 5 increases, causing the moisture and medicine in the airflow to condense into water droplets and adhere to the side walls of the channel. This collision mechanism between airflows accelerates the condensation process of water vapor, efficiently separates the medicine from the airflow, and effectively avoids environmental pollution problems.

[0026] Specifically, the guide block 8 is triangular, the first side of the guide block 8 is connected to the side wall of the airflow channel 12, the second side is provided with the arc groove 15, the arc groove 15 faces the direction of the airflow, the baffle 10 is provided opposite the third side, and the third side of the guide block 8 is parallel to the baffle 10. The guide block 8 plays a role of guiding, the airflow flows through the area between the baffle 10 and the third side of the guide block 8, and is diverted to both sides by the diverter block 9 when flowing to the rear, and the arc groove 15 guides one of the airflows to collide with the other airflow, prompting the condensation of water vapor, thereby separating the medicine in the airflow to avoid polluting the environment.

[0027] Specifically, a plurality of metal sheets 16 are provided between the baffle 10 and the side wall of the airflow channel 12. The metal sheets 16 are parallel to the baffle 10, one end of the metal sheets 16 is connected to the side wall of the airflow channel 12, and the other end is located on a plane parallel to the side of the diverter block 9. The metal sheets 16 are spaced 0.1 to 1 mm apart, and the liquid medicine condensed on the metal sheets 16 is adsorbed on the metal sheets 16. The condensed medicine flows downward from the gaps between the metal sheets 16 and finally gathers at the bottom of the metal sheets 16, preventing the medicine from evaporating under the action of the airflow. The plane where the other end of the metal sheet 16 is located is parallel to the side of the diverter block 9. When the airflows converge and collide, the condensed medicine easily enters the gaps of the metal sheets 16, thereby promoting the adsorption and recovery of the medicine.

[0028] Specifically, a plurality of water collecting grooves 17 are provided at the bottom of the recovery tank 6, and the water collecting grooves 17 are provided along the bottom of the inner wall of the recovery pipe and the bottom of both sides of the isolation cylinder 7. The water collecting grooves 17 are connected to the drainage grooves 18, and the drainage grooves 18 are connected to the drainage pipe 19. The medicine condensed in the recovery tank 6 flows to the bottom along the isolation cylinder 7 or the recovery tank 6, and the medicine gathered at the bottom flows along the drainage grooves 18 to the drainage pipe 19, and is finally discharged from the drainage pipe 19.

[0029] Specifically, the drain pipe 19 is provided with a valve 20. When the valve 20 is closed, the airflow is prevented from being discharged from the drain pipe 19.

[0030] Specifically, a refrigerator 21 is provided at the center of the recovery tank 6. The refrigerator 21 is used to cool the inside of the recovery tank 6 to promote the condensation of the reagent.

[0031] Specifically, the refrigerator 21 includes a heat conducting sheet 24, a heat conducting pipe 23 and a cooling box 22. A refrigerant is arranged in the cooling box 22. The refrigerant is ice or an ice crystal box. The cooling box 22 is connected to the heat conducting pipe 23. The heat conducting pipe 23 is connected to the heat conducting sheet 24. The refrigerant is used to cool the cooling box 22, and the heat conducting sheet 24 is cooled through the heat conducting pipe 23. When the airflow contacts the heat conducting sheet 24, the temperature is reduced, thereby promoting the condensation of the medicine in the airflow.

[0032] Specifically, the heat conducting sheet 24 is a C-shaped structure, and a plurality of the heat conducting sheets 24 are nested to form a flow channel through which air can pass, and the openings 11 of adjacent heat conducting sheets 24 face in opposite directions. The airflow passes between the heat conducting sheets 24, fully contacts and exchanges heat with the heat conducting sheets 24, and promotes condensation of the agent in the airflow.

[0033] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. The protection scope of the present invention should be based on the protection scope of the claims.
